C. BRIGHT, residing at .,Clarence, in the county of Shelby and Stat-e o'Missoiiri,` have invented a new` and useful "-l-Antiskid-Rudder for Autos, ofl which the Bef it known that I7 ROSWELLI -uifollowing is' al specification.

wat i.

,.'risfIhe device forming the subject matter of @this application is adapted to be assembled with a motor Apropelled vehicle forthe pur-' inveiit'ion contemplates the use of a Q tcally movable rudder, and one object of ifive'tion to th t' the sa1newill cut into'the soil as the hieljfis advanced, the rudder being so con- ,strucftediat its rear end that it will secure 'd "etai ehi 'movef rearwardly.

noth` rffobject di the invention is to pro-v de' ovelineans for assembling the rudder for" vei-tical lino vementi on the Vrear axle easingi` i other object ofthe invention is to provdewnovel means for holding the rudder yiel'dably uplifted.V

A furthervobject of the invention is to provideno'vel meansfor actuating the rnd der vertically.

It isw'ithin the,I province ofthefdisclosure to impyove generally and. to enhance the utility of devices of that type tov `which the present invention appertains.

Withythe above and other objects 1n View Which will appear as the description proceeds, the invention resides in the combina tion and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made Within the scope or' what is claimed, `without departing from the spirit ofthe invention.

Fig. l is a sectional detail wherein parte appear 1n elevation, the'view `delinea-ting lthe actuating spring for the rudder, Vand the meansWherebyfthf spring is sustained.

In tlieklrawings there is'shown a portion 'cfa vehicle 1 which may embody a foot board 2, a rear axle Acasing 3, rear wheels 4 'anda differential `'asing 5. Mounted upon the 'rear axle casing 3'upon each side .of the differential 'casing 5 are' tivo-part clamps, each clampy includi: 1g a front member 6 and a rear member?, tlie constituent members of the tivo clampsbeiigimited, above and below theaxle'casing v3 by means of bolts 8 or otherwise. The rea f members 7 the casing clamps are provid ed with vertically `disposed,` horizontally spaced ears 9 the ears of the respective clamps carrying pivotbolts l0 Vand 11. The bolt 11. is somewhat longer than the bolt lard embodies ahead 12. Nuts 14 are thread ed onto the bolt 11v4 and bear against th'e o 1i;ei'faces of the ears 9 of one clamp member, as will vbe understood readily fr on'i Fig. i'.

The invention vcontemplates the use of a mulder 15 prefer-ali y in the `forni of a rigid plete ci2 metal unH l. Bilbo ving'a rifid lower edge .2301. y The rear'` u ppe edge of tile rudder y .joiifnivardlv Elined, to' form a1 i earth entering point 1b., tlie l'unc`tion of Which will he made manifest hereinafter] The torn-arde lower edgt of the rudder 15 is up Wardly inclined to forni an earth entering prow 17. The edges 30 and 1T are sharpened. Secured at their rear ends to opposed faces of the rudder 15, as shown at 18, are upwardly extended, diverging arms 19 and 20. mounted to swing o n the pivot bolt 107 between 'the ears 9 of the clamp wherewith the pivot bolt 10 is assfmbled. provided with ari eye 22, mounted to swlng on the pivot bolt 11, between the ears 9 .of

the clamp fthrough`\,ivhich the pivot bolt passes. The arm '5mt-is Supplied with a curved? depending' er tension 23, passing overy The arm 19 terminates in an eye 21,-

The arm 20 is 25 is formed into an eye engaged by one of.;

the clamp bolts 8n The other end 26 of the sprin 24 is formed into a hook or other attac ing element interengaged with the arm 20 as shown best in Fig. 2. It will now be understood that the function ofA the spring 24 is to elevate the rudder 15, so that the same normally stands outof contact with the ground, as indicated-in Fig. 1.

T. e invention comprises a. connection in the form of a wire rope 2T, the rear end of which is attached to the lowerl end of the extension 23 which constitutes ay part of an arm 20. The forward end of the rope 27 is attached to the lower end of a pedal 28 of any desired form, fulcrumed as shown at 29 upon the foot board 2 o r upon some other accessible portion of the vehicle 1.

In practical operation, when the pedal 2S is moved, the connection 2? will be actuated, the same tilting the arms and 19 through the instrumentality of the extension 23. Thus-the rudder 15 is lowered into contact with the ground, the spring 24 being put under tension. lVhen the pressure on the pedal 28 is relieved, t-he spring 24 will react on the arm 20 and lift the rudder 1,5 outof contact with the ground, and into the position shown in Fig. 1. Because the forward 4 edge of the rudder 15 is inclined as shown at 17, the rudder will cut readily into the ground when lowered. It -is to be observed that the rudder 15 is in the form of a rigid plate, the lower edge 30 of which is rigid, continuous, sharp, and well adapted to enter the ground and to retain asecure hold thereon, the construction above outlined being far more eliica cious than one in which rollers or other anti-friction elements are journaled on the rudder-adjacent its lower edge. Owing to the fact that thel r'udder at its rear endterminates in an earth entering point 16', the rudder will bite into the ground,

fd y,Should the vehicle start to move rearwardly.

' l The prima f function of the ruidder, hw-

ever, as wil be understood from'the drawings, is to preventv the vehicle from skidding laterally.

It is' to be obseaffed that one end of the spring 2l is assembled with one of the clamps, the other und of the spring being connected with thev arm 20 of the rudder 15. Asa consequence, no part of the spring is connected to the rf-hicle body proper. It is therefore unnecesfl; y to work any changes in the vehicle bod in order to provide a connection for the spring 24, the spring constituting a part of the rudder mechanism which, generally,7 considered, may be connected with the rear axle casing 3 without changing the stanafard construction thereof.

Having thus described the invention, what is claimed is In a device of the class'described, a. vehicle embodying a raar axle casing; clamps assembled with the axle casing; plvot elements in the clamps; a rudder; diverging arms attached to the rudder and mounted on the pivot elements, one arm embodying an extension prolonged above the axle casing and extended vertically with respect thereto; a spring surrounding one pivot element,

one end ofthe spring bein'g unit'ed with the clamp which carries the said pivot element,v
